1) USA-269 [41724/16047A] has performed its first maneuver, aimed at
   raising the perigee and decreasing the inclination. The maneuver
   occurred at the apogee of 00:33UT on July 31, 2016. Fitting the
   positional measurements above, with an added fixed position of
   USA-269 at that apogee results in this orbit:

USA-269 Post-maneuver 1                               6197 x 35796 km
1 41724U 16047A   16213.02313657  .00000000  00000-0  00000-0 0    09
2 41724  12.9770 324.6811 5406231 179.9707 179.5719  1.91693105    06
# 20160731.94-20160731.95, 12 measurements, 0.008 deg rms

   More observations are required to constrain the orbit without using
   the fixed position. However, this orbit should be good enough to
   recover it until it makes the next maneuver. The delta-V of this
   maneuver was 437 m/s.
